CIRCULAR RING-GAGE.

Patented Sept. 26, 1916.

Application filed July 1, 1913. Serial No. 776,861.

' Be it known that I, LEO F. Lmsnn, citizen of the United States, residing at McKeesport, inthe county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements 1n Circular B ng- Gages, of which the following is a speclfica- 1 tion.

This invention relates to improvements in gages and more specifically to circular ring gages. Y

The object of my invention is to provide a ring gage which may be used not only for determining the exact size of a ring, but more especially the exact portion of a ring which must be removed in order to'reducc the' ring to a given size, resulting 1n ac-- curacy and the saving of considerable time in making rings of the proper size.

W1th'the above and other ob3ects in view, my invention conslsts in the combination, ar-

rangement, and details of construction. dis-' closed in the drawings and specification, and then more particularly pointed out in the ap'pendedelaim'.

Referring to the drawings, wherein similar reference characters designate similar parts throughout the respective views: Figure 1 is 'a fraginental detail. view of my circular ring gage enlarged and laid flat, while Fig. 2 is a side elevation of the same. 1

Referring to the drawings, which are merely illustrative of my invention, 1 designatesthe metal casing or tube portion of the, preferred type of my ring gage, while 2 is the core thereof which terminates in a handle 3. Said tube 1 is tapering and has marked or stamped thereon a chart so scaled as to gage the size of rings, said scale comprising a line 4 running the length of said tube, said line 4 being divided by parallel lines 5 spaced apart, disposed at right angles to said line 4, and running around the tube portion 1, and-are so numbered as to indicate the slze of a ring at the IGSPECtIVB' lines 5. My novelty lies in the marking and numbering as a part of said scale and upon each of said lines tothe right and sizes to which a ring may be reduced. This is accomplished with my gage by slipping the ring over the tube to the point whereit fits the gage. This indicates the present size of the ring. The ring is then marked to the right and to the leftof the line 4 at the number or mark which indicates the size to which the ring is to be reduced. By severing the ring at the points thusmarked, removing the portion thus' out out, and againpressing the ends of the severed ring together, the ring will be found to fit the gage at the exact size to which. it was to be reduced.

Haying now described and pointed out the new and useful features of my invention, I

scale comprising a line extending along the length of said bodyportion, a plurality of circnmferentially extending lines spaced apart along the length of said body portion, and a plurality of dissecting marks spaced apart upon said circumferentially extending lines and upon both sides of said first mentioned line, excepting only the first circumferential line nearest the smaller end of said tapering body portion. t

In testimony whereof I affix my signature in presence of two witnesses LEO F. LIESER.
